Silicone oil freeze dryer

The silicone oil freeze dryer adopts intermediate medium circulation technology. Temperature control for shelf life, uniform and controllable temperature of the board layer, smooth board layer, and good conduction of cold and heat; Equipped with compressor secondary start timing protection and pressure overload protection system;

　　Silicone oil freeze dryerMain features:

1. Structural design that complies with biopharmaceutical standards. The internal corners, surface roughness, shelf flatness, and internal materials of the freeze-drying chamber all meet pharmaceutical standards;

2. The control system is stable and reliable. Adopting PLC programmable logic control system and 10 inch color touch screen, the system runs more stably and reliably, with friendly human-computer interaction, Chinese English language conversion, and can achieve remote control on mobile phones and computers, with three-level permissions;

3. Real time display and recording of vacuum degree, cold trap temperature, material temperature, shelf temperature, and forming freeze-drying curves. Data is stored once per minute, and material and equipment condition data can be continuously recorded. It supports offline browsing, analysis, printing, and storage of data, and is equipped with USB communication interface and TCP interface;

4. The freeze-drying process can be controlled. The freeze-drying process is automatically controlled by programmable programs, and semi-automatic or fully automatic control can be switched in real time to achieve parameter control throughout the entire freeze-drying process;

5. The design of separating the freeze-drying chamber from the cold trap chamber not only meets the standards of pharmaceutical grade pilot testing machines, but also greatly improves the water capture efficiency and capacity;

6. The silicone oil freeze dryer adopts intermediate medium circulation technology. Temperature control for shelf life, uniform and controllable temperature of the board layer, smooth board layer, and good conduction of cold and heat;

7. Dual machine cascade refrigeration technology. Adopting a fully enclosed compressor unit and standard green and environmentally friendly cold coal, the refrigeration is fast, the cold trap temperature is low, and the water capture ability is strong;

8. Equipped with compressor secondary start timing protection and pressure overload protection system;

9. The drying room adopts high pressure and low temperature resistant aviation acrylic material with high transparency doors, which can observe the entire process of material freeze-drying changes;

10. Shelf silicone oil refrigeration and heating, with adjustable and controllable temperature and rate, using PID fuzzy control calculation to achieve in-situ pre freezing and sublimation functions;

11. The cold trap has an automated frost function;

12. Configure the hydraulic system;

13. Optional negative pressure aeration system interface. Built in 0.2 μ m filter element to reduce secondary contamination of samples, can be filled with nitrogen or inert gas;

14. Optional cleanroom installation methods and provide cleanroom installation solutions;

15. Optional vacuum degree adjustment function to explore freeze-drying process;

16. Optional eutectic point online testing function can be used to better optimize the sample sublimation process;

17. Optional computer upper computer real-time monitoring and chart recording;

18. Optional intermediate isolation butterfly valve: Conduct pressure rise testing and vacuum degree adjustment;
